Look, it's a cute idea. But I think if you want to watch a good crime/fairytale blend, you're better off watching Hoodwinked (2005).

Once Upon a Crime is a whodunnit lazily mashed together with a Disney-esque Cinderella story (I'm referring the animated one, not the kickass Whitney Houston one). The characters have no depth, nor is the world-building overly creative. I don't mind a bit of oddball humour but it ended up being annoying.

It's a shame. I think if the creators had thought outside the box a bit, this could've been decent. I got bored and dropped it around 30min in.
